STANLEY SAUVAGE, OF CHICAGO, ILLINOIS.

COOKER.

Specification of Letters Patent.

Patented Feb. 17, 1914.

Application filed July 5, 1912. Serial No. 707,675.

To all whom it may concern:

Be it known that I, STANLEY SAUVAGE, a subject of the King of England, residing at Chicago in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cookers, of which the following is a specification.

This invention relates to a cooker adapted to be used in connection with a stove or range employing gas, oil or the like, as a fuel, and the principal object of the invention is to provide a device of the class described which is simple, durable and inex pensive in-construction and eflective and efficient in operation.

A further object of the invention is to provide a device of the class described in which there is an even distribution of heat which results in an economical use of fuel and an effective and eflicient use of heat for cooking materials of different kinds.

For the attainment of these ends and the accomplishment of other new and useful objects, as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts generally shown in the accompanying drawing and described in the specification, but more particularly pointed out in the appended claims.

In the drawing Figure 1 is a cross sectional view of a cooker constructed in accordance with the principles of my invention; Fig. 2 is a plan view of the base of the cooker taken on the line 22 of Fig. 1.

Various kinds of cookers are employed in connection with gas stoves and the like, which are adapted to be removably positioned over the gas flame to utilize the heat therefrom. These cookers are more or less wasteful of the heat of the flame and usually the flame is so directed that one portion of the cooker becomes heated much more rapidly than the other, resulting in an uneven distribution of the heat and consequently in the uneven cooking of materials disposed therein. The present invention is designed to overcome these difliculties and to present a cooker in which heat is evenly distributed so that materials disposed therein may be evenly cooked.

Referring now more particularly to the drawing and in the present exemplification of the invention, the cooker comprises two separable portions, a bottom member or pan 4 and a top or cover 5. One of these members, preferably the top, is larger than the other so that they may be disposed one within the other to economize space when not in use as a cooker. In their preferred form, as exemplified in the drawing, the members 4 and 5 are rectangular in structure, but, of course, may be of any desired or suitable shape. They are composed of sheet metal or other non-combustible material, preferably diverging toward the edges or rims so that the pans will nest together more readily. The upper edges of the pans or members are preferably rounded over metal strengthening bars 6 in the wellknown manner to stiffen the pans and to provide a more rapid construction. The edge or rim of the larger member, in this exempliflcation the top 5, is provided with a shouldered portion 7 adjacent the edge of the rim so that the rim of the cover 5 will extend beyond the rim of the base member 4 forming a close and substantially closed contact between the pans, and at the same time pressing a bearing surface for the cover upon the base member 4. The top of the lid or cover 5 is provided with a lifter 8 of any desired or suitable construction, preferably in the form of aloop which may be folded against the top of the cover. Disposed within the cover 5 and in contact with the top thereof is a layer or pad of nonconductive material 9. This material is held in position by means of a plate 10 secured to the top of the cover in any suitable manner, as for example, by means of the fastening devices 11. This non-conducting material 9 preferably consists of some such material as asbestos, mineral wool or the like, which is a well-known non-conductor of heat.

I The base member 4 is preferably slightly less in depth or height than the top or cover 5 so that in nesting the member 4 within the member 5 it will be entirely disposed within the latter member. The bottom of the member 4 is formed with an opening 12 through which the heat from the flame passes, the edges 13 being folded over and secured together for additional strength. The sides of the member 4 are pressed inwardly to form ridges 14. These ridges 14 are adapted to provide a support for a plate 15 disposed within the pan and preferably adjacent but spaced from the top thereof. The pan is also provided with handles 16 by means of which the pan may be moved and which are foldable against the sides of the pan when it is nested within the cover 5.

The plate 15 disposed within the pan 4 and resting upon the ridges 14: is a support for the materials to be cooked. A wire stand 17 is preferably disposed on top of the plate 15 upon which the articles to be cooked are placed. This stand may be of any desired or suitable construction, the ob ject being to support the material at a slight distance from the plate 15 so that the heat may pass readily beneath the ar ticle or material to be cooked and so that the heat will be evenly distributed on all sides thereof. This plate 15 is of such a shape that the heat arising through the opening 12 is allowed to pass upwardly to the space formed by the cover 5. For this purpose the plate 15 may be provided with perforations 18 in the edges of the plate and in the present exemplitication of the invention the corners are removed or cut away at 19 so that the heat may pass readily through the opening 12 and upwardly through the pan 1 around the edges of the plate 15. To direct the heat toward the edges of the plate 15, a conical member 20 is disposed beneath the plate 15 with its apex extending downwardly. This conical member 20 is held in position in any suitable manner, such, for example, by means of a bolt 21 with its head engaging the plate 15 and a nut movable on the threaded portion of the bolt to hold the conical member in position. Disposed beneath the plate 15 and held in position by the conical member 20 is a pad or plate of non-conducting material 23, preferably the same material as the pad 9 in the top or cover, which is held in place by the engagement of the conical member with the edges of the pad 23.

In operation the base member +1 is positioned over the flame or burner, from which the heat is to be derived, with the plate 15 resting on the ridges 14: and the conical member 20 disposed below the plate, as shown in Fig. 1. The wire rack is positioned upon the plate and the material to be cooked is placed upon the wire rack. The cover 5 is then placed over the material to be cooked and allowed to remain for any desired or proper time. The heat in entering through the opening 12 in the base member at strikes the surface of the conical member 20 and is directed toward the edge of the plate so that the direct impactof the heat does not strike the plate 15 at its center. This prevents the plate 15 from becoming more heated at one point than at another and the air space formed by the conical member 20 together with the pad 3 of non-conducting material causes the surface of the plate adjacent the center to be heated evenly. Diverting the heat toward the sides of the plate 15 causes it to be projected through the openings at the sides of the plate and around the plate at its cutaway portions, so that the heat is evenly distributed in the space formed by the cover. Since the material to be cooked is spaced from the plate 15 by means of the wire stand 17, access may be had upon all sides of the article or material to be cooked, as well as on the top and bottom thereof, which results in the heat being evenly applied and evenly distributechthe plate at the top of the cover being separated from the outside of the cover by means of the pad of non-conducting material 9 which prevents the top of the cover fr m1 becoming unduly heated, directs the heat which arises from the openings 18 and from around the plate 15 downwardly after striking the plate 10 and retains the heat given to the plate 10 within the cover so that the heat does not escape so readily, resulting thereby in an economical and efficient use of the heat.

Vhile I have thus described the preferred embodiment of my invention, it is evident that those skilled in the art to which this appertains may make various changes in the construction, combination and arrangement of the several parts without departing from the spirit and scope of my invention.
